Abstract

The embodiments in the invention provide a single droplet evaporation experimental device. The device comprises a first cavity and a second cavity, wherein the first cavity is arranged directly abovethe second cavity and connected with the second cavity by a vertical channel, a droplet generating module is arranged in the first cavity for generating single droplets having good consistency and causing the single droplets to drip through the channel to the second cavity under the action of gravity, the second cavity is provided with quartz hanging silks which are arranged below the lower opening of the channel for hanging single droplets dripped from the first chamber. Since the single droplets are dripped from the first cavity, it is not necessary to open any cavity to feed single dropletstherein, thereby realizing the problem of accurate generation and suspension of the droplets in a high pressure environment. Moreover, since it is not necessary to open any cavity, it does not interfere with the temperature and pressure environment in the cavity, so that the accuracy of generating single droplets is greatly improved.

Description

technical field [0001] The invention relates to the technical field of internal gas, in particular to a single droplet evaporation experimental device. Background technique [0002] With the increasing shortage of fossil energy and the pressure of environmental protection, energy conservation and emission reduction has become the core concept of governments in formulating environmental protection policies and regulations. Driven by this concept, researchers in the engine field have successively proposed advanced engine technologies such as advanced supercharging technology, high-pressure injection technology, and optimized combustion. When internal combustion engines apply these advanced engine technologies, they will produce higher cylinder temperature and pressure without exception, and changes in the environment in the cylinder will change the process of fuel evaporation and oil-gas mixing, so it is necessary to control the high temperature in the cylinder. Research on f...
